child death Implements BaseParticleRenderer. Definition at line 296 of file spriteParticleRenderer.cxx. References _aabb_max, and _aabb_min.

BaseParticleRenderer * SpriteParticleRenderer::make_copy (  void   )  [virtual]

child dynamic copy Implements BaseParticleRenderer. Definition at line 102 of file spriteParticleRenderer.cxx. References NodePath::find(), and NodePath::is_empty().

int ReferenceCount::ref (   )  const [inline, inherited]

Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count.

Sets the properties on this render from the geometry referenced by the indicated NodePath. This should be a reference to a GeomNode; it extracts out the Texture and UV range from the GeomNode. Definition at line 121 of file spriteParticleRenderer.cxx.

Definition at line 191 of file spriteParticleRenderer.I. References _sprite_primitive.

void SpriteParticleRenderer::set_ll_uv (  const TexCoordf &  ll_uv  )  [inline]

Sets the UV coordinate of the lower-left corner of all the sprites generated by this renderer. Normally this is (0, 0), but it might be set to something else to use only a portion of the texture. Definition at line 68 of file spriteParticleRenderer.I. References _color, and INLINE.

Does some easy checks to make sure that the reference count isn't completely bogus. Definition at line 328 of file referenceCount.I. References INLINE. Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref (   )  const [inline, inherited]

Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count.
